LocalDateTime isAfter() method in Java
It can be checked if a particular LocalDateTime is after the other LocalDateTime in a timeline using the isAfter() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object that is to be compared. It returns true if the LocalDateTime object is after the other LocalDateTime object and false otherwise.
A program that demonstrates this is given as follows −
Example
import java.time.*;
public class Main {
public static void main(String[] args) {
LocalDateTime ldt1 = LocalDateTime.parse("2019-02-20T11:37:12");
LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30");
System.out.println("The LocalDateTime ldt1 is: " + ldt1);
System.out.println("The LocalDateTime ldt2 is: " + ldt2);
boolean flag = ldt1.isAfter(ldt2);
if(flag)
System.out.println("
LocalDateTime object ldt1 is after LocalDateTime object ldt2");
else
System.out.println("
LocalDateTime object ldt1 is before LocalDateTime object ldt2");
}
}Output
The LocalDateTime ldt1 is: 2019-02-20T11:37:12 The LocalDateTime ldt2 is: 2019-02-18T23:15:30 LocalDateTime object ldt1 is after LocalDateTime object ldt2
Now let us understand the above program.
The two LocalDateTime objects ldt1 and ldt2 are displayed. It is checked if the LocalDateTime object ldt1 is after the LocalDateTime object ldt2 in the timeline using the isAfter() method. The returned value is displayed using an if statement. A code snippet that demonstrates this is as follows −
LocalDateTime ldt1 = LocalDateTime.parse("2019-02-20T11:37:12");
LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30");
System.out.println("The LocalDateTime ldt1 is: " + ldt1);
System.out.println("The LocalDateTime ldt2 is: " + ldt2);
boolean flag = ldt1.isAfter(ldt2);
if(flag)
System.out.println("
LocalDateTime object ldt1 is after LocalDateTime object ldt2");
else
System.out.println("
LocalDateTime object ldt1 is before LocalDateTime object ldt2");
